title: Results of aortic valve replacement for aortic stenosis with relatively low transvalvular pressure gradients.
abstract: Fifty-two patients with low gradient critical aortic stenosis who underwent aortic valve replacement were found to have a perioperative mortality of 11% and an 8-year actuarial survival of only 29%. No hemodynamic variables, including valvular resistance, predicted long-term outcome, and the only clinical variable that predicted long-term survival was the absence of coronary artery disease.
